REFRIGERATORPCAR DRI? PAN.

Application filed April 28, 1923. Serial No. 635,404.

To all whom t may concern.'

Be it known that I, KARL I?. Nrsraar, a subject of Great Britain, and a resident of Chicago, in the county of Cook and State of Illinois, haveV inventedL certain new and useful Improvements. in Refrigerator-Car Drip Pans, of'which the following is a description, reference being had to the accompanying drawing, which forms al part of my specification.

My invention relates to means for draining the water, resulting from the melting ice p or refrigerant, from the bunkers or ice containers at the end or ends of railway refrigerator cars; that is to'say, the invention, more specifically stated, relates to the bottom ofthe bunker and the drip pan disposed throughout the bottom of the bunker whereby the water is caused to fiow toward and through a defined path or channel and be drained therefrom.

One object of the invention is to provide means whereby the drip Vpan will not only be reenforced but at the same time provide a rigid and firm connection or foundation for the posts or uprights of the bulkhead of the car and also provide support for the ice holding container or basket.

Another object of the invention is to pro Vvide means whereby the water will be prevented from splashing orbeing thrown over the forward edge of the pan, while the car is in transit or shifted, and therefore prevented vfrom passing through the air'circuvlating opening at the bottom of the bulk- Lhead into the car proper where it is likely to damagethe lading.

A further object of the invention is to provide a' drip pan with an outlet or drain conduit` of such Construction as will insure.

- a constant draining of the water'while at the same time'oblviating the possibility of becoming clogged by straw or other foreign matter lodging in the drain conduit.

VThe above enumerated objectsas well as 'the advantages inherent in the construction y will all be more readily comprehended from` the detailed description of the drawing, wherein :-y i

lthe lower end of an ice bunker of a refrigerator ear, provided with my improved drip P311. 'f i V"'Figgmre 2 isv s; vertical :sectional: view taken IFigure 1 is a'vertical ,sectional view ofon the line 2 2 of Figure 1, looking in the direction of the arrows.

Figure 3 is a sectional plan, with portions broken away, of one cornerof the ice- .bunker and drip pan.

In order to illustrate my invention, I have shown the lower part of an ice bunker usually formed at the ends of refrigerator cars as disclosed by the side and end walls 10 and 11 of the car and the bulkhead 12; the walls and bulkhead being formed in the usual manner with suitable insulating material and with air circulating passages at top and bottom of the bulkhead; the bottom opening being shown at 13 in Figure 1.

In the particular exemplification of the invention, where the lower end of the ice holding container is shown, the side walls consist of suitable wire mesh indicated at 1l; while the bottom of the container comrises a suitable number of transversely disposed members, preferably in the nature of channel beams as shown at 15, and these beams also support the ice holding racks 16,-which are preferably removably secured in place by hook-bolts as at 17 the hookbolts being disposed through registering apertures in the flanges or sides of the channel beams. Y

The door 18 of the bunker, namely at the end of the car, is depressed below the floor 19 of the main portion of the car so vas to provide a well in the floor, commensurate with the construction and of depth in keeping with the depth of my improved pan, in order that the pan may be disposed below the floor level of the lading holding portion of the car.

The well in the floor is intended to receive my improved drip pan shown at 20. The pan is intended to be disposed throughout the entire well inthe floor or bottom of the bunkerithe pan being preferably of suitable sheet metal, with a' flat bottom which restson the floor planks of the bunker. The pan is provided with an upstanding rim 21 of predetermined height, which is preferably' arranged rearward of the sheathing or flashing'22 on the walls of the car `so`as to cause the water to low down into thevdrip pan. i Y

The bunker loor`18 is provided with a longitudinal depression, extending from side yto sident' the carA for the purpose of; receivx ing theV channeled portionv or trough suitable perforations"` 26.""The" 'pipe eX- which isV arranged preferably at the `longitudinal center-line of the pan. 'lfhev channel ori trough 23'E is *preferablyj arranged Vto. Y extend throughoutjthe length of the panso as to cause the Water to drain from opposite sides toward the trough from which it is permitted to vdrain by a suitable: drain piye' 24.

he drain or outlet pipe 24 is preferably. Vformed with Van arcuate closed upper end 255V to prevent solid -matter becoming "lodged in the pipe, and the pipe fora 'predetermined 'distance atthe upper end 'above`v the pan -bottom 'is' providedW-ith' a plurality of tends upyvarda' distance corresponding with the depth 'of vthe'"p'a'n'at thetioughportion thereoii'iin order'that' a sufficient `drain may *be*providedA fAt a 'point `beneaththe'pe'ry'forati'ons26 and beneath` thejpan bot-torn the vpipe spread-@af'was @aangeeft-611m '27 'firmly secured "thereto for the" "purpseof supporting 'the 'l drain'- pipe 24 "in, place; 4 the fiange' Vor' '27'y beingi'pre'ferably'disposed 'between the 'ber "erthe 'bunker and-'the hottom'of'the pan as'shovvn.

Viith this" construction 4Vthe outlet pipe acts as aY trapVv orstrainer to preventstraw or 'otherY solids ventering the outlet opening, While atthe same time, vbecause of'its perforated end extending above the bottom of the pan, affording'an ample drain'to" prevent excessive accumulation' of'vva'terV inthe an. l

The fiooryl) ofthe main portion of the ear, at 4the Yair circulating'opening 13, beneath the` bulkhead 12, 'is provided with a Splash plate' 28, which 'consists v"preferably of a metallic strip or plate of suitableWidt-h removablyv secured to the main floor 19,'s`that the free longitudinal edge Vthereof is arranged to overlap the upper edgje'ofthe drip pan-20 along the frontl or bulkhead longitudinal side. The floor 19 is 'preferably Y kerfed to receive'the plate 28 in order that it may 'extend flush 4with themain lfloor; theplate being of length to extend throughout the length of the pan andoffwidth sufficient to overlapthe forvvard 'edge' of the l'pan to `a considerable extent'asshovvn in #Figure l. v y Y 1,-",

:The rdrip pan is provided with metallic Vblocks or 'shoes' 29, 30, which are arranged With. the lower ends of the shoes preferably located Within and riveted or rigidly se cured to the drip pan and disposed upwardly to support the ice holding container or basket. The'blocks or shoes 29 are arfrangedin the'corne'rs of the drip'pan at 'what maybe termed Vthe rear side, namely adjacent to the end v'vallof the car, andl the'vre- .v forereenforce the upstanding flanges'or 'sides of" the pan ,"vvhile the blocks or shoes 30, at the 'foriv'a-rd or'bulkhead side of thefpaiu dus to the splash pratese, and there@ that the' drip' pani extends slightly 'beneath-'nie bulkhead, are arrangedv at a"V slight"'fclista1ice i from the fifvard 'side1 'orv Y 'asshqwa in: "Fgue .1." Tlie'bloc'k's' orshes' are preferably formed lowerk ends in order 'that the majr pennen f yofthe kshoes above theipan 'sides-l extend lflush With'the side and nd'valls ofwtl'ie 'bunker' and therefore permit' the upstaiidiig sidesof the4 pan to be disposed between 'the' blocks ors'hoes landthe Wallsof vthe ,bunker and at the same time permit thethinfslieet or flashing 2() to also verlap'the Vupstanding sides or' flanges ofthe drip p'an asshovvn at"the'left'in`Figure`1.` i

'The 'blocksl or shoes are adapted tobe sefoundation for the posts.

- Thebottom of the drain pipe 24 is shown provided with a cup .member 32, suitably secured'thereto, to provide a Water sealand Vthus prevent the inflow of air through the conduit; With the Water sealarranged-iba neath the' floor,l namely von the' earV exterior, the cupv member 32 is not only easily accessible, but cleaning "of the vmember may be done'vvith'out' entering thecar'f "T With `the'"depressed vfloo'r and construction of -drip pan asshovvn and {.lesc'iibed",j it l is J apparent that the;v air circulating''p asage beneath the bulkhea'dis `unobstructed 'and the chilled air allowed to circulate alongftlie thefrfrefmfeefw new meegaat the fleeingwldingiflobrsaek;- a pda-ion whereof Sv Shown at 33.
